NONBREAKABLE BUTTON'.

Applica/dgn inea February 1o, 1921. seria; No. 443,887.

e hereby declare that the following is a full,

clear, and exact description thereof.

My invention refers to buttons for garments and the like, and it has forits object to provide as a new article of manufacture a simple,economical and effective button, which is composed of a compound such asrubber or the like,.whereby the button is uniformly flexible.

The primary object of the :button is to prevent breakage in washing orpassing through wringers or the like, also to prevent the cutting ofthreads which attach the buttons to the garment, and to prev'entslippage of the button.

Another object is to mold or form the button from material coloredthroughout, to meet the various trade requirements. A further object is'to provide a button wherein wire material or other inserts orreinforcement is avoided, it being understood that the button, whencomposed of rubber compound, is vulcanized at such temperature that theheat from flatirons, 'boiling water or acids can be effectuallyresisted.

With the above and other minor objects in view, the invention consistsin certain peculiarities of construction, combination of parts as arehereinafter set forth with reference to the accompanying drawings andsubsequently claimed.

In thedrawings:

Figure l represents a plan view of a standard type of button made inaccordance with my invention, and

Figure 2 is a cross section of the same, the section being indicated byline 2-2 of Figure l.

`Referring b-y characters to the drawing, 1 represents the body of acircular button having four apertures 2 therein of ordinary type for thepurpose of attaching the button to a garment in the usual manner, the

' apertures being formed in a counter-sunk circular recess upon one faceof the button, while the opposite face of said button is convenedslightly, as shown at 3, the con-- veX face and the flat face, beingconnected by a rounded edge 4. The button is molded,

pressed, or cut preferably from a compound of rubber that is vulcanizedsufliciently to resist high temperatures, but is at the same time quiteflexible or pliable. Obviously, the thread which passes through theholes for retaining the button to the clothing will not cut, due to itscontact with the resilient material. In other words, the thread iscushioned in its contact with the button walls.

Obviously, I may vary the shape of the button indefinitely and also thenumber of attaching holes, without departing from the spirit of myinvention. In practice, it has been found, by actual test, that thebutton composed of rubber compound and vulcanized sufficient to resisthigh temperatures will lastindeiinitely, under ordinary usage andconditions. Furthermore, there is no breakage of these soft buttons whena garment is ironed or pressed by the ordinary type of sad-iron or 'anelectric heated iron. It has also been found that the button will notdeteriorate when sub-A ject to boiling water or acids.

It is to be noted that the button is thickened adjacent itscentral'portion to provide the requisite strength and that it graduallytapers towards its edge to provide the additional flexibility adjacentthe edge. Further the central portion of the button may be recessed soas to provide a depression to prevent the securing threads fromprotruding above the upper plane of the button. This thickened centralportion will provide the necessary body to resist severe stresses evenwhen the button is subjected tothe heat of ironing. l

To sum the mattei' up briefly, the button is primarily a soft flexibleor pliable new article of manufacture, non-breakable, and the life ofthe button is therefore insured, even though it is subjected to thesevere usage to which the ordinary type is put. It is also within thescope of my invention to moldv the button from any plastic material,which is capable of flexibility or pliability, and furthermore, buttonsof this character can be colored to suit the trade requirements, thecoloring matter being added to the compound in process of nmnu'factureso that it strikes through the entire body of the article.

l claim:

A new article of nmnufucture comprising a button composed ofhomogeneous, permanently flexible,o non-absorbent material, and

having a flexible edge and having lapertures adjacent itsfoentralportion. p

In testimony that I claim the foregoing 10 I have hereunto set my handat Milwaukee, in the county of Milwaukee and State of Wisconsin.

HANS KANOFFSKY.
